Genuine Rolon HPORC 393 brass chain & sprocket kit for Honda H’ness CB350 / CB350RS.
Correct 14T front sprocket, 34T rear sprocket and 104-link chain setup for compatible Honda CB350-family replacement fitment.
Fitment warning: This kit is for H’ness CB350 / CB350RS-type fitment. Do not assume fitment for CB350 Classic, CB350RS variants with modified gearing, CB300R, CBR250R or other Honda models without matching the exact teeth count, chain length and hub pattern.
Rolon HPORC 393 is a brass chain and sprocket kit for Honda H’ness CB350 / CB350RS applications. The verified setup is 14 teeth front sprocket, 34 teeth rear sprocket and 104-link chain. This is the main fitment detail to check before ordering because Honda’s CB range includes multiple motorcycles with different chain-sprocket requirements.
This kit is useful when your CB350 starts showing drivetrain wear symptoms such as khat-khat chain noise, chain slap, jerky low-speed pickup, rough throttle response, tight spots, rusted chain links, hooked sprocket teeth or frequent chain adjustment. Replacing the front sprocket, rear sprocket and chain together helps restore smoother power transfer and prevents premature wear caused by fitting a new chain on worn sprockets.
HPORC 393 is positioned as the brass Rolon kit for the CB350 application, giving riders a premium replacement option over a basic chain-sprocket set. It is best suited for daily commuting, highway cruising, touring and relaxed riding where smoothness, correct fitment and long-term drivetrain health matter more than experimenting with gearing.
Use this kit only when your motorcycle matches the 14T/34T/104L setup and the front sprocket spline/rear hub pattern match. Under The Hood supplies genuine fitment-focused spares with careful packing and buyer support so riders get the correct kit code instead of a mismatched Honda CB-series chain kit.

Installation & Maintenance Notes

- Check front sprocket spline and rear sprocket hub pattern before dismantling.
- Maintain chain slack as per the Honda owner’s manual for your exact CB350 model.

- Avoid direct high-pressure water jet on the chain and sprocket area.

- Inspect rear hub dampers during installation; worn cush rubbers can still cause jerks even after fitting a new chain kit.
FAQ
Will Rolon HPORC 393 fit my Honda H’ness CB350?

Is HPORC 393 a brass chain kit?
Yes. HPORC 393 is positioned as the brass Rolon chain-sprocket kit for compatible Honda CB350 applications. Final chain finish should still be checked against the current physical box before dispatch.
Is this X-ring or O-ring?
This listing does not claim X-ring or O-ring construction unless confirmed from the current Rolon packaging. The confirmed customer-facing details are HPORC 393, Honda H’ness CB350 / CB350RS, 14T front, 34T rear and 104-link chain.

No. Do not assume fitment. CB300R and CBR250R use separate kit applications and must be verified by exact kit code, teeth count and chain length.
Should I replace only the chain?
No. For best life and smooth running, replace the chain, front sprocket and rear sprocket together.
Why buy from Under The Hood?
